Jung, known affectionately as “The Korean Zombie” for his relentless style, was knocked out by a George Roop head kick in his last bout. His record stands at 0-2 in the WEC, and he’ll likely face expulsion from the company should he lose to Yahya.

Yahya is a former bantamweight title challenger, having lost to Chase Beebe in his bid for the title at WEC 30.

“Fight for the Troops 2″ is headlined by a lightweight contender’s bout between Kenny Florian and Evan Dunham.

Campuzano is returning to the Zuffa fold after winning an August fight outside of the company. He went 1-2 in his previous run in the WEC, scoring a victory over Coty Wheeler while losing to Eddie Wineland and Damacio Page.

Pace debuted in the WEC in September, losing a unanimous decision to Demetrious Johnson.
